java - Play Framework 2.4 (Java) + Hibernate + JUnit : org. hibernate.engine.jdbc.spi.SqlExceptionHelper - 池已关闭

Question

我想要一个这样的测试。

package database;

import org.junit.Assert;
import org.junit.Test;
import play.libs.ws.WS;
import play.libs.ws.WSResponse;
import play.test.WithApplication;

import static play.mvc.Http.Status.OK;
import static play.test.Helpers.running;
import static play.test.Helpers.testServer;

public class UserTest extends WithApplication {

    private static final long TIMEOUT = 4000;

    @Test
    public void testUser() {
        running(testServer(3333, app), () -> {
            WSResponse response = WS
                    .url("http://localhost:3333/api/user/1")
                    .get()
                    .get(TIMEOUT);

            Assert.assertEquals(OK, response.getStatus());
        });
    }
}

但是，在运行激活器测试时，我不断收到以下错误。由于某种原因，连接池在执行测试之前关闭。这里可能是什么问题？

从文档:
注意:每次运行测试或仅测试时都会派生一个新进程。新进程使用默认的 JVM 设置。可以将自定义设置添加到 build.sbt。例如:

也许你可以尝试禁用它

将以下代码放入您的 build.sbt

fork in run := false
fork in Test := false
